CORN-HUSKING MACHINE..

SPECIFICATION forming' part of Letters Patent No. 761,562, dated May 31, 1904.

Application filed January 24, 1903. Serial No- 140,366. (No model.)

To (ZZZ whom it may concern:

.Be it: known that I, GEORGE LnsLEY WAOK- EROW, a citizen ofthe United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Corn-Husking Machines, of which the following is a specification.

My invention relates to improvements in corn-husking machines, and pertains especially to that class of such machines in which the ears are stripped from the standing stalks and husked during the progress of the machine. So far as I- am aware, the machines of this class as heretofore constructed have been provided with snapping-rollers which were located in the stalk-passage, and various expedients have been devised in such machines to direct the ears to the husking-roll- -ers;-but as the ear-directing devices .must also be operative in the path of the stalks and in front of the snapping-rollers considerable difficulty has been experienced in properly directing the ears without interfering with the stalks.

The object of this invention is'to provide a form-of construction in which the snappingrollers are located at one side of the stalkpassage and the stalks bent laterally to the line of such rollers and passed between them for the separation of the ears, the stalks being then permitted to swing backwardly into position as the machine moves forwardly.

In the following description reference is had to the accompanying drawings,'in which Figure 1 is a plan view of my invention.

Fig. 2 is a detail view of the snapping-roller driving connections. Fig. 3 is a detail side view of the stalk-feeding chains in their relation-to each other. :Fig. 4 is a front elevation. 5 i I Likeparts are identified by the same refer ence characters throughout the several views.

A main frame 1 and an auxiliary frame 2 are connected together by arches 3, leaving a stalk-passage underneath the arches. The

frames are supported upon a traction drivewheel 5 and a grain-wheel 6, with which they are respectively connected, the wheel'5 being fast on a main driving-shaft 7 suitably journaled in frame 1.

9 and 10 are the snapping-rollers. These are journaled in the main frame, with a downward, forward, and lateral incline and with their lower ends adjacent to the stalk-passage formed by arches 3. The main frame 1s provided with a forwardly-extending inclined tapered platform 15.} The auxiliary frame is also formed with a forwardly and laterally extending guide 16, theframe 15 and guide 16 operating like a broad open fork to gather the fallen stalks into the stalk-passage.

-A gathering-chain 18 revolves in a substantially horizontal plane along one side of the stalk-passage and is provided with fingers 19, which project into the passage and travel rearwardly therein. These fingers engage and push the stalks rearwardly toward the snapping-rollers. A yielding bar 20, projecting rearwardly from the'auxiliary frame and bearing upon a resistance-spring 21, is

used to-insure the engagement of the stalks by thefingers. A series ofv slats 23 are also secured to the auxiliary frame and project from their point of attachment backwardly, upwardly, and across the stalk-passage. into proximity to the upper snapping-roller, the

lower slat 23 projecting into proximity with.

the lower end of such roller and the others I beingof progressively-increasing length andcurved, so that the series of slats taken together occupy a curved plane of somewhatsimilar form to that of the moldboard of a plow. The function of these slats is to bend the stalks laterally and cause them to pass between the snapping-rollers. Revolvingfeeding-chains26 and 27 are provided-with feeding-fingers 28 and arranged to cooperate with 'the slats 23 in directing the stalks between the snapping-rollers. The lower ends of these rollers are tapered, as shown, and the chain 26 extends between the tapered ends of the rollers above the feeding chain 18 and revolves in a vertical plane. The chain 27 also revolves in a vertical plane, but has an upward pitch from near the lower front portion of the'main frame to a point in front of the lower snapping-roller. The feedingfingers of these chains engage the stalks which are bent over by the slats 23 and carry them to a position where they arecaught between the snapping-rollers. The detached ears drop upon a conveyer-apron 30, whereby they are delivered to husking-rollers 31, of ordinary construction. From the husking-rollers the ears are delivered to a conveyer 32, which elevates them to a point of final discharge into the box of a wagon traveling adjacent to the husker. The stalks after having passed between the snapping-rollers are permitted to straighten and are left standing as the machine moves forwardly.

Motion is transmitted from the main driving-shaft 7 to the lower snapping-roller through the beveled gear-wheels 35 and 36, tumbling-rod 37, and beveled gear-wheels 38 and 39. The upper snapping-roller is driven from the lower one by spur gear-wheels 40 and 41. The gathering-chain 18 runs over end sprocket-wheels 42 and 43 and is driven from the main shaft by a sprocket-chain 44, shaft 45, beveled gear-wheels 46 and 47, and vertical shaft 48. The sprocket-pinion 49 of the feeding-chain 26 is mounted on the shaft and motion transmitted to the feeding-chain 27 through the chain 26, its front sprocketwheel 50, shaft 51, and sprocket-wheel 52 thereon. The upper or rear end of the chain 27 runs over an idle sprocket 53 adjacent to the lower snapping-roller. The husking-rollers are driven from the main shaft by beveled gear wheels 55 and 56, shaft 54, sprocket-chain 58, and the interacting spur gear-wheels 57 of these rollers. The apron 30 is mounted on rollers 59 and 60 and the roller 59 driven from the husking-rollers by a sprocket-chain 61. The conveyer 32 is driven from the shaft 54 by a sprocket-chain 65, which drives the lower conveyer-shaft 66.

While I have illustrated the motion-transmitting connections above described, it will be understood that any suitable mechanism for driving the working parts of the machine may be employed.

In operation the machine is driven along the rows of corn with the arches straddling the hills. The gathering chains and fingers run backwardly at a somewhat greater speed than the forward movement of the machine and carry the stalks against the curved slats, which bend them over into the path of the snapping rollers, which are arranged one above the other in position to receive the stalks. The fingers of the feeding-chains 26 and 27 catch the bent stalks and cooperate with the slats in directing them between the snapping-rollers. The remaining operations of the machine are obvious from the illustration. The ear-conveying apron covers a broad space and is adapted to receive all ears and convey them to the huskers, and the operation of the husking-rollers and ear-conveyor is well known in the art.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
